People with claustrophobia tend to feel heightened levels of distress over dark or confined spaces or feelings of being trapped. They may also exhibit intense fears of suffocation. With that in mind, it's also somewhat common for people to experience claustrophobia episodes during an MRI scan.
When not properly accommodated during an MRI, claustrophobic patients may experience panic attacks, which can bring on increased heart rate, difficulty breathing, chills, sweating, and other distressing symptoms.
Instead of a tube, an open MRI has scanners on the sides with an opening on top, making it an outstanding option for those who have claustrophobia. The patient lays comfortably on a platform while the scanners on the sides do all the work.
For patients who may experience claustrophobia during an MRI scan and require prophylaxis, the University of Wisconsin Department of Radiology suggests the use of Lorazepam (Ativan, Temesta), a short-to-intermediate duration benzodiazepine.
Counting numbers or listening to music: Counting slowly or listening to a soothing melody can help distract you and make the time pass quickly while you are in the scanner. Talk to the Technician: In most instances, you can speak to the technician throughout most of the procedure.
Patients with certain conditions that may prevent them from staying still in the MRI machine, such as claustrophobia, anxiety, or a condition that causes physical pain, may have an MRI with anesthesia. It is also common for children to have an MRI with anesthesia, since it is often difficult for them to remain still.
What medications are used? Propofol will be given through an I.V. to induce sleep. This medication has a short duration of action and a rapid recovery time and is administered to make sure you remain asleep during the entire MRI study.
Magnetic resonance imaging (MRI) has become one of the most important diagnostic tools in many areas of medicine. Several studies have shown that MRI causes severe anxiety in 37% of patients, even those who state that they are not claustrophobic, and 5–10% cannot complete MRI due to claustrophobia [7].
The technologist will ask you several times to hold your breath and stay still to be able to get good pictures. You will be asked each time to hold your breath for twenty seconds. This part is very important because we cannot do the MRI examination, if you cannot hold your breath long enough.
Background: Magnetic Resonance Imaging (MRI) is associated with high levels of anxiety in many patients which may interfere with image quality and increase examination time.
Many MRI procedures don't require your head to go inside the machine at all, but if you need a head or upper spine MRI, you'll appreciate the fact our machine provides a full 12 inches of clearance between your face and the wall – relieving stress for our patients with claustrophobia.
Depending on what needs to be scanned, your test will take between 20 to 90 minutes.
People often make up scary images in their head and start picturing the MRI machine as a claustrophobic trap that they won't be able to handle. You might feel more comfortable when you see an Open MRI. The imaging center often allows patients to have a tour of the room where the MRIs are conducted.
An MRI scanner is a short cylinder that's open at both ends. You'll lie on a motorised bed that's moved inside the scanner. You'll enter the scanner either head first or feet first, depending on the part of your body being scanned.
A single scan may take a few seconds or 3 to 8 minutes. You may be asked to hold your breath during short scans. The total scan lasts 15 to 90 minutes, depending on the size of the area being scanned and how many images are needed. You'll be moved out of the scanner when your scan is over.
MRI is also contraindicated in the presence of internal metallic objects such as bullets or shrapnel, as well as surgical clips, pins, plates, screws, metal sutures, or wire mesh. If you are pregnant or suspect that you may be pregnant, you should notify your physician.
It's important that patients remove all clothing prior to their MRI exam. We ask patients to remove: All outer clothing, including shoes. Bras or any undergarment that could have metal in it.
Since the MRI machines are magnets, it is best to not apply deodorants, antiperspirants, perfumes, or body lotions before the examination. These items contain metals that might interfere with the magnetic field inside the MRI machine and cause you to have distorted images and wrong results.
Gadobenate is a gadolinium-based contrast agent (GBCA). Gadobenate is given by injection before an MRI scan to help find problems in the brain, spine, and other parts of your body.
An open-bore MRI machine is open on both ends and enclosed by a tube-like bore; it offers a wide opening of approximately two feet. A conventional MRI is also open on both ends but has a smaller opening.
Approximately 10 % of people who attempt an MRI are unable to complete it because of claustrophobia.
CT scanners are different from MRI scanners and use very little x-ray radiation, unlike MRI scanners. CT scanners are open on both sides, and you can completely see around yourself during a scan. Claustrophobic patients might welcome CT scans more because they don't have to be in an enclosed space.
